This is mostly a bug fix release, though there are a few new and improved drivers. Source: http://www.gdal.org/dl/gdal-1.3.1.tar.gz http://www.gdal.org/dl/gdal131.zip Docs / Web site: http://www.gdal.org/dl/gdal131doc.zip Test Suite: http://www.gdal.org/dl/gdalautotest-1.3.1.tar.gz The major news with this release is that the "Next Generation" Perl, Python and Ruby bindings are now considered ready to use, though I'm sure there will be some additional improvements to them in the coming months. I would like to give out a special thank you to Ari Jolma (perl), Charlie Savage (Ruby), Kevin Ruland (Python + overall NG work) and Howard Butler who have put in a huge amount of effort on these bindings. If we can get champions for Java, C# and PHP that are willing to brave the dark depths of SWIG, I'm sure we can make good progress on them too.

PCRaster Driver: - libcsf is now included as part of GDAL. - PCRaster enabled by default on win32. - --with-pcraster=internal option now supported on unix (but not yet default) VSI Virtualization: - The "large file API" (VSI*L) has been re-engineered to allow installing additional file handlers at runtime. - Added "in memory" VSI handler so that now any driver using VSI*L functions for data access can operate on in-memory files. - PNG, JPEG and GeoTIFF drivers upgraded to work with in-memory support. Raster Attribute Tables: - Implemented new Raster Attribute Tables support. See the GDALRasterAttributeTable class for more information. Erdas Imagine Overviews: - Erdas Imagine driver upgraded to support building internal overviews. - Generic overview handler updated to support overviews in Erdas Imagine format for any file format. Set USE_RRD config option to YES to enable. gdalwarp: - Added proper support for "unified source nodata", so the -srcnodata switch works well. RIK Driver: - New Swedish format driver implemented by Daniel Wallner. JPEG Driver: - Substantial improvements to EXIF support. MrSID Driver: - Updated with proper JPEG2000 support as JP2MRSID driver, including encoding with ESDK. - Updated to support MrSID Version 5.x SDKs. PNG Driver: - Fixed serious bugs with 16bit file support. - Added NODATA_VALUES to identify RGB sets that indicate a nodata pixel. OGR 1.3.1 - Overview of Changes ------------------------------- Reference Counting: - OGRSpatialReference and OGRFeatureDefn now honour reference counting semantics. - Note that, especially for the OGRFeatureDefn, it is now critical that all drivers be careful with reference counting. Any OGR drivers not in the core distribution will likely crash if not updated. ESRI Personal Geodatabase Driver: - New driver implemented for ESRI Personal Geodatabase (.mdb) files. - Uses ODBC, enabled by default on win32. ODBC Driver: - Updated to support binary fields. - Updated to support WKB geometry fields. - Updated to support DSN-less connections. S57 Driver: - Added support for Inland Waterways, and Additional Military Layers profiles From gould at lsi.uji.es Sat Oct 1 10:20:32 2005 From: gould at lsi.uji.es (Michael Gould Carlson) Date: Sat, 01 Oct 2005 10:20:32 +0200 Subject: [Freegis-list] global connection project Message-ID: <1128154831.433e46d003d72@webmail.uji.es> http://www.cs.cmu.edu/~globalconn/index.html gigapan sounds cool. http://www.cs.cmu.edu/~globalconn/gigapan.html ciao, M Gould From scalar at c-a.at Thu Oct 6 11:45:05 2005 From: scalar at c-a.at (Philipp Wassibauer) Date: Thu, 06 Oct 2005 11:45:05 +0200 Subject: [Freegis-list] Looking for GIS expert Message-ID: <4344F221.1000708@c-a.at> Hello, I am starting up a new Community Portal using Google Maps API.

It is clearly some sort of projected coordinate system. Till you know that, the .tfw isn't going to do you much good. By the way, the .tfw is saying that the center of the top left pixel of the image is at (3408200,5635500) and that each pixel is 200x200 (likely 200 meters by 200 meters). But without the coordinate system, you can't relate that to latitude and longitude values. Once you do have the coordinate system, you can use the PROJ.4 (or another projections package) to convert between lat/long values and projected coordinates. Then use the .tfw values to turn the projected values into pixel/line locations. BTW, do you happen to have a .prj file too?

Googling on "tfw format" I found the following on http://www.asmail.be/msg0055111818.html: --- A sample TFW file opened up would look like: +6.00 -0.00 -0.00 -6.00 1709053.00 807714.00 Line 1 - Cell size in the "X" direction Line 2 - Insertion point in the "X" direction Line 3 - Insertion point in the "Y" direction Line 4 - Cell size in the "Y" direction Line 5 - Easting value of insertion point "X" Line 6 - Northing value of insertion point "Y" Note that sign on line 4 will tell you if the insertion point is the upper left or lower left corner. A positive means the "Y" values are increasing upwards and therefore, the registration must be starting at the bottom or lower corner. Vice-versa for a negative sign. --- Also, the GeoTIFF format spec can be found at: http://www.remotesensing.org/geotiff/spec/geotiffhome.html > I need transform standard GPS coordinate (eg.: 50d04m55sN 14d26m03sE) to > pixel coordinate in my map (eg.: 256px,414px aproximately) and backwards. Unfortunately, knowing the TFW format won't help you with converting your GPS coordinate. The TFW file doesn't contain coordinate system information, so you don't know the projection method, datum, etc. But once you convert it into the same system used in your TIFF file, the tfw parameters can be used to locate it on your image accurately. - Bill Thoen From freegis at pbox.cz Thu Oct 6 16:42:59 2005 From: freegis at pbox.cz (Petr) Date: Thu, 06 Oct 2005 16:42:59 +0200 Subject: [Freegis-list] TFW format In-Reply-To: <931f8ea90510060728r46272cb9y53e0cb2870243648@mail.gmail.com> References: <434530B1.9020707@pbox.cz> <931f8ea90510060728r46272cb9y53e0cb2870243648@mail.gmail.com> Message-ID: <434537F3.2070201@pbox.cz> I think that coordinate system is S-42.

You first need to convert your coordinates from degrees, minutes, seconds to decimal degrees, and then run them through some sort of coordinate conversion software (Try GEO at http://opensourcegis.org/). To convert 50d04m55sN 14d26m03sE to decimal degrees, you use the following formula: d + m/60 + s/3600 where d is your degrees, m is your minutes and s is the seconds. Then if the longitude is west, make your longitude negative, and if your latitude is south, make your latitude negative. To convert the coordinate you list above to decimal degrees, it's longitude is 14 + 26/60 + 3/3600, or 14.4341667, and latitude is 50 + 4/60 + 55/3600, or 50.0819444. Then you just need to convert (14.4341667, 50.0819444) to S-42 coordinates (and I don't recognize that coordinate system, so I can't help you there) with some coordinate conversion tool.

To do so, I'm using INM software ( http://www.faa.gov/about/office_org/headquarters_offices/aep/models/inm_model/ ). I need digital elevation files for this model, the only problem is that it accepts ONLY .3cd (binary format by Micropath Corporation http://www.micropath.com/ ) and .3tx (text format by Micropath Corporation) files, and I can't find support for them. I have an elevation .grd file (Golden Software Surfer) but I can't find a way to translate/convert it in a .3tx file containing terrain elevations covering a one-by-one degree area; below there's a description of the .3tx format. The .3tx text format: Lat Long Elevation Elevation Elevation ...etc... where -Lat is the latitude of SW corner (integer degrees) -Long is the longitude of SW corner (integer degrees) -elevation is terrain elevation MSL (integer meters) The first line in the file defines the southwest cornerof the one-by-one degree area. North latitude and east longitude are positive integers; south latitude and west longitude are negative integers. The SW corner must be on integer degrees. There must be exactly 1201*1201=1442401 lines following the first line. Each line contains one number - the elevation, in integer meters, of the terrain above mean sea level. The elevation of the SW corner is the first integer, the elevation that is 3 arc-seconds to the north is the next integer, and so on until the top edge (integer degree latitude) is reached. Then move 3 arc-seconds to the east, start at the bottom edge, put in another 1201 elevations while moving north, and so on until the file is finished. So, if anyone of you can help me telling me about a program, a tool or a software that can manage my Surfer .grd file and convert it into a .3tx or a .3cd one, I'll be very thankful! By the way, thank you a lot in advance Davide Borelli ( emo.da at jumpy.it ) ________________________________________ Il tuo partner ? un bravo amante?

Bill, A consortium of uses recently funded me to implement read-only support for ESRI Personal Geodatabases. All you need is the normal Microsoft Access ODBC driver - no ESRI software. This is built into the latest FWTools builds from: http://fwtools.maptools.org/ You could translate all the layers in a personal geodatabase to a directory of shapefiles like this (from the FWTools Shell): ogr2ogr out_shape_dir mydata.mdb Some info on the driver is available at: http://www.gdal.org/ogr/drv_pgeo.html The "Shape" column is reported as an OLE object but if read as a BLOB it matches the geometry format that appears in the .shp file of a shapefile. PS. Thanks for asking the question in a public forum. It gives me an excuse to "toot my own horn".

Message-ID: Hi, I'm working on GIS software for PDA. I want to add open/save project feature and I'd like to use ArcXML format (ArcPad project format is based on ArcXML too). As I see, ArcXML reference includes only copyright information about the document itself, so that's not exactly what I need. My question is: Am I allowed to use ArcXML as a project format for my own application? Users of my application will be able to do following operations: - open/save project created by my application - create and save project in my application and open it in ArcPad - create and save project in ArcPad and open it in my application Could anyone give me a piece of advice regarding to the copyright and terms of use of ArcXML?

Dieter, I have not attempted to implement Personal Geodatabase writing. It would be non-trivially more challenging than the reading but I have talked to someone who has done it in a proprietary product and so I know it is achievable. However, it would require a substantial amount of additional development.

The RFC and other discussion papers are potentially "specification track" but considered to immature for adoption as finished specs. They are made public in the hope of gathering broader feedback. Note that many discussion papers will stay that way forever because there isn't enough interest in seeing them through to proper specifcations or because they are essentially auxilary material. But some are definately intended to evetually emerge as specifications. Well, thats my take anyways. I'm sure there are OGC folks who could give their take on things.

I believe so, given that you do not reuse significant parts from their specification documents and that they do not have enforable patents on the techniques you need. It helps if you use the format for interoperability reasons, too. > Users of my application will be able to do following operations: > - open/save project created by my application > - create and save project in my application and open it in ArcPad > - create and save project in ArcPad and open it in my application > > Could anyone give me a piece of advice > regarding to the copyright and terms of use of ArcXML? Sound legal advise you base a business on should come from a lawyer. Note that you could ask ESRI of course, too. There is a lot of Free Software that implements copyrighted specifications, so this is more a general question.

The format seems simple enough and usually elevation data is not complicated. I would suggest that you write a small script that does the conversion for you. Try to export the .grd file into something simple where you have the format specification for and then write a small script reading this and writing out the other stuff in the language of your choice.

Thanks for your reply. I've asked some authorities and it seems I can use ArcXML specification in my application. Yes, the main reason is interoperability with i.e. ESRI ArcPad which uses ArcXML as a project format. Something OT but interesting: I discovered that ArcPad and ArcXML (or its subset used by ArcPad) is not XML conformant!

Claire has built a Google map based system, getting locations from IP addresses. I suggested a fully Open Source based system might be appropriate, and could even be a OS GIS suite showcase (applications and global raster & vector data) if anyone wanted to take it that far. Postgres/Postgis/mapserver seems the obvious mix, though I admit it is not the only one. ka-map could also fit in there... as well as plenty of other OS web-mapping related packages. A small minority of Postgres users seem to use spatial data, and this could present & foster a Postgres based solution for anyone interested in adding location functionality to existing Postgres implementations. So, is anyone out there in OS GIS world interested in becoming part of a team to help put this together?

One thing to keep in mind is that the postgresql website is statically mirrored onto a number of different servers, so any solution we come up with will ideally allow itself to that. I believe a google maps system can do this (we can mirror the javascript code and the location/data file on all mirrors and the google map will work with it as is), which is why I originally went with that type of solution. -- Robert Treat Build A Brighter Lamp :: Linux Apache {middleware} PostgreSQL From arnulf.christl at ccgis.de Fri Oct 28 12:44:11 2005 From: arnulf.christl at ccgis.de (Arnulf Christl) Date: Fri, 28 Oct 2005 12:44:11 +0200 Subject: [Freegis-list] Re: [GENERAL] Map of Postgresql Users (OT) In-Reply-To: References: <7def66b8e277ec3dcfb0e90f001194fa@zeesource.net> <20051027094158.W82309@storm-user.niwa.co.nz> <200510262102.27259.xzilla@users.sourceforge.net> Message-ID: <436200FB.4090400@ccgis.de> Claire McLister wrote: > Good point.

Sounds like this task should be solved using WMS and WFS services. Google is cool but in order to foster both Open Source and standards (OGC) we would suggest to use e.g. MapServer as WMS to produce the maps and GeoServer as WFS to manage geomtries. Those OWS services could then be included in any OWS client, web interface, etc. Everything is there and ready to go, the effort to get it to run should be minimal. Our clients usually operate PostgreSQL databases with several million geometries - those 500 to 600 markers could be hosted on any antediluvian box and still be fast. You will know what to about mirroring, we would probably suggest to implement P2P - read Ward Cunninghams ideas int he keynote at the Wikimania conference this summer... We have done the user mmapping Mapbender users with tooltips, direct link to the website, etc. You can have a look at it on the project homepage http://www.mapbender.org Its done Wiki-style so that users can enter their own position (use the blue flag) or remove or edit any position (use the i-button). No user accounts yet but security and authentication is in place and have just not yet been necessary (still waiting for spatial spam...) We will spread word about spatial data management using PostgreSQL/PostGIS with MapServer, GeoServer etc. at the http://www.opendbcon.net (database fundamentals) on Nov. 8. and 9. in Frankfurt/Main, Germany. This idea is on short notice but i would be really very excited if i could show the map there! We suggest the following alterantive actions: - It should be easy to add a geometry_column to the existing PostgreSQL database which alredy has the positions. Add a GeoServer WFS to access the geomtry and a MapServer for WMS display. - Alternatively send Paolo or us or both the geo-positions and we add them to our existing OWS infrastructure (that will takt a few hours of work only). Beause there is not so much time until the conference this would just be be a prototype which should in the long run move to the PostgreSQL or PostGIS homepage or Wiki or both. Yet another idea: Mediawiki (the Wikipedia software) is also right now introducing geometries to the Wiki database - obviously also using PostgreSQL/PostGIS. This would be another cool multiplier.. and there we also meet with Google again.

I looked at the mapbender site, and it looks like it has the basic functions except the password protection, which you will probably need at some point:-) The performance from here (California) was slow, and the map image did not look as good as Google's. I suppose we have better map images available? I could not find Cunninghams talk on P2P style wiki's, but seems to me that it would be too much work for a simple web page. Ideally, we'd just want to have a static map with possibly Javascript popups. That way, the performance can be good and the web site doesn't become that onerous that the pg www group kicks us out. So, a question to you and Palo: Can you generate such static map (along with Javascript code) from Mapserver?

There's some working code, and I'm just improving it from "proof of concept" stage to pre-production level. The code I'm working on is an extension to MediaWiki. It is independent of the article storage. I'm sure storing everything in one DB would be better from a design point of view, but it's easier for us to scale if we keep things apart. Especially new features like these where we've no idea about the performance impact. If you're improving MediaWiki's Postgres support we'd of course be happy to get your patches into the main code tree.
